Support Reshade Mods

[effs]

Reshade uses INI files, too, so if we want to support them or prevent them from being miscategorized as INI mods, add some detection..

[Bladehawke]

The first problem with adding actual detection is Vortex's own handling of files. As it stands, this extension currently seems to drop INI files into the folder they are in in the archive, so a properly set up Reshade should be packaged as bin\x64\my_awsome_reshade.ini.

Of course most of them aren't currently packaged that way and a lot of them are also including their old shaders from previous version in the download

[Bladehawke]

I was thinking that we could wrap this into the INI handler since we don't get access to the destination path until the install phase.
